Losing my Audio Midi Network Connection with iPad

I have been trying to set up my iPad to connect to my Macbook Air over a computer-to-computer network to run a midi remote app called Midi Designer with Mainstage 2. The connection will work for a few minutes, but if there is no signal sent from the iPad for a minute then the connection is lost. I have my iPad set to never sleep, as well as my computer. Are there any other settings I need to change to keep the network active over longer periods of time?
